SmartGuard Blade Technology for Added Protection

At the heart of the K 770 SmartGuard is its innovative extended blade guard. The SmartGuard system is designed to reduce the likelihood of incidents during use by guiding the operator to stay within the recommended cutting zone. This intelligent design not only increases jobsite safety but also reinforces proper cutting habits, making it particularly valuable in training scenarios or high-risk environments.

Powerful Cutting with SmartTension™ System

Equipped with a 5 hp engine and Husqvarna’s semi-automatic SmartTension™ system, the K 770 SmartGuard ensures optimal belt tension for maximum power transfer, extended belt life, and reduced maintenance. This means more time cutting and less time adjusting or replacing parts—ideal for high-efficiency crews and fast-paced job sites.

The saw also boasts an excellent power-to-weight ratio, reliable starting, and impressively low vibration levels, all of which combine to reduce operator fatigue and maximize daily productivity.
